Seeing as the Switch is still nice and fresh, I'm guessing this may be some kind of intro offer to play on people's fear of missing out. It adds a comfy bulge to the underside of both joycons. I do wonder whether this setup works well for playing with sideways joycons i.e. Multiplayer games.
I believe Orzly have other Switch items for discount. I've bought other Orzly items in the past, and have found them excellent, I expect these to be no different.
